CORN-PLANTER CHECK-ROWER.

SPECIFICATION forming part of Letters Patent No. 248,285, dated October 18, 1881.

Application filed August2G,1881 Model.

To all whom it may concern: I

Be it known that I, GEORGE W. BROWN, a citizen of Galesburg, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain newand uset'ul Improvements in Corn-Planter Check-Rowers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form apartof this specification.

This invention relates to check-row attachments to corn-planters of the class in which a stretched knotted wire or cord is used toactuate the check row devices; and the invention consists in constructions and combinations hereinafter described and claimed.

In the accompanying drawings, which illustrate my invention, Figure 1 is a top plan, showing the parts in relative positions hereinafter fully described. Fig. 2 is a top plan, the parts shown in different relative position from Fig. 1. Fig. 3 is a detail view, hereinafter referred to. Fig. 4 is a perspective of one ofthe oscillating ends of one of the jointed forked levers.

Beferringto the drawings by letters, the same letter indicating the same part in the different figures, letter A represents a bar, which extends across the corn-planter, and to each end ofwhich a device similar to that shown in the drawings may be attached as check-rowers are ordinarily attached.

B. B are elbow-levers, journaled to a plate, 0, which is secured to the bar A, and'on which the working parts are mounted. The ends B of the elbow-levers are connected by a rod, D, so that when the end B ofeither lever is swung in one direction the end B of the other lever will thereby be swung or moved in the opposite direction. 1

The end B of each elbow-lever is formed in two parts, B B. The outer orforked end part, B, is hinged at b,"near its mid-length portion, to the part B, so that it may oscillate or swing in same plane or parallel plane with the movement of the elbow-lever. One end of the part B is forked in the ordinary the seed slides.

manner, and preferably has a shoulder or projection, b, on its front side, to receive the knot on the check row chain, as hereinafter described; but this shoulder may be dispensed with, if desired. The other end of the part B has a stud, b, on its lower side, which projects downwardly into a curved groove or slot, E, in the plate 0, and each stud I) should preferabl y be provided with an anti-friction roller, 6.

The slots E for the two parts B are curved in opposite directions to each other, their forward end portions being straight, or about straight, and converging towardeach other as they pass rearward to about their mid-length portion ,from whence they curve outwardly from each other and forward, as plainly shown in the drawings.

F F F are respectively the ordinary knottedwire guide-pulley, guidefinger, and plate at the forward part of the machine, and F is the ordinary guide-pulley at the rear,-covered by a bridge, f, with an oblique slot, f, through which the knotted wire may be passed to the pulley by slightly deflecting it (the wire) in the ordinary manner.

G is a rod extending from the end B of one of the elbow-levers to the bar which connects and operates the planter seed-slides, (not shown in the drawings,) whereby movement is imparted to the slides in the evident manner.

The rod G may be'journaled to either of the series of holes 9 in the bar B, for the purpose of adjusting the length of throw of the seedslides.

In operation the planter is drawn along by the side of the stretched check-row or tappet wire 11 in the ordinary manner, and said wire H has knots or tappets h, of any desired kind, at distances apart on the wire equal to the distances of hills 7 of corn to be planted. The planter moving in the direction shown by the arrow, and the hinged forked arms standing in the relativepositions shown at Fig. 1, thetappet h on the wire will come in contact with the forked end of the part B, which is forward of the other part B, and thereby force the part B with which it is in contact toward the rear, and by means of the rod D force the other part B toward the front, and by means of this rod imparts a-movement or throw to The next tappet on the check rowwire will then act upon the part B" which is now forward, and,forcing it to the rear, will operate the seed slides and again bring the same one forward which is shown as forward at Fig. 1, and ready for a repetition of the operation first described. As each hinged forked arm passes forward the stud b, sliding in the groove IE, will swing the part B into the position shown by the forward part B in full lines at Fig. l, which position will be favorable to receive the tappet h in the forked end of the part B. As the hinged forked arms swing, the one forward and the other rearward, their respective studs 1), moving in their respective slots IE, will swing the parts B, so thattheycan pass each other, as shown at Fig. 2. As each hinged forked arm approaches the last end of its throw its stud 1), working in the slot IE, will swing the part B, with its forked end, to the rear, and thus allow the tappet which was in contact therewith to escape, as shown by dotted lines, Fig. 2, and also full lines at Fig. 1.

The parts 13 may be constructed differently from what I have shown in the drawings, and may be differently hinged to the parts B from what I have shown, and the slots E may be differently formed to accomplish substantially the same results, and hence I d d lfmit my claims to the special constructions of th ese parts, except wherein so expressed in the claims; but

What I claim as new is 1. I11 a check-r0wer, oscillating arms having their forked ends upon which the tappet-wire acts hinged to the main portion of the arm, substantially as and for the purpose specified.

2. Oscillatingforked levers for check-rowers, formed in two parts-an oidina-ry oscillating part and a forked end part hinged thereto so as to swing in same plane or parallel planessubstantially as and for the purpose specified.

3. A vibrating or oscillating lever for checkrowers, having its outer or forked end hinged to its main portion, substantially as and for the purpose specified.

4. A vibrating or oscillating lever for checkrowers, having its outer or forked end hinged to its main portion, and adapted to be oscillated on the main portion by means of a curved slot, in which a stud on one end of the forked end portion slides, substantially as and for the purpose specified.

5. Oscillating forked arms for check-rowers, having hinged outer ends, which swing to allow them to pass each other, substantially as described.

6. Oscillating forked arms for check-rowers, having confronting ends, each with its outer or forked end hinged to its main portion, so that it may swing to allow the arms to make their throws without touching each other, substantially as and for the purpose specified.

7. In combination with forked arms or 10- vers having their outer forked ends hinged to the main oscillating portion, the slots or grooves E, adapted to swing the forked end parts so that they may pass each other, substantially as and for the purpose specified,

8. In combination with the oscillating levers or arms having their outer ends hinged to their main portions, the slots E, curved substantially as described, and adapted to swing the outer forked end portions of the levers, so that they may receive the tappets on the tappet-wire, may pass each other, and swing to release the tappets, substantially as and for the purpose specified.

9. In combination with the tappet wire or chain, forked arms or levers having outer hinged ends actuated by the tappets on said wire, and swung so as to receive and release the tappets and pass each other, substantially as and for the purpose specified.

10. In combination with the tappet-wire and arms on which the tappets act, which arms are adapted to impart movement to the seed-slides of a corn-planter, and have their outer ends hinged to their main portions, grooves or slots adapted to swing the outer ends of the forked arms, so that they may pass each other.

11. In a checlcrower, oscillating arms having outer ends, B, hinged to their main portion, and provided with studs I), which slide in grooves E to swing the parts B, substantially as and for the purpose specified.

12. In acheck-rower,oscillatingforkcd arms having confronting ends adapted to be acted on alternately by a tappet-wire, and having their outer ends hinged to their main portions and adapted to be swung by slots E, substantially as and for the purpose specified.

13. In com bination with theoscillatingforked arms B and grooves E, the parts B, hinged to the parts B, and having one end forked for the reception of the tappets and their other end adapted to slide in the grooves E, substantially as and for the purpose specified.

14. In combination with the oscillating arms B and tappet-wire, the swinging ends 13, having forked ends and shoulders I), substantially as and for the purpose specified.

15. In combination with the oscillating arms or elbow-levers, connected by a rod, D, the slots E, adapted to swing the outer hinged ends of said elbow-levers, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
